Ultrapure water equipment
EDI equipment is applied after the reverse osmosis system to replace the traditional mixed bed ion exchange technology (MB-DI) to produce stable ultrapure water. Compared with mixed ion exchange technology, EDI technology has the following advantages:
- Stable water quality.
- Easy to realize fully automatic control
- No shutdown due to regeneration
- No need for chemical regeneration
- Low operating cost
- Small plant area
EDI (Electrodeionization) is combined with reverse osmosis and other purification devices to remove ions from water. Ion exchange resin in EDI module can be divided into two parts, one part is working resin and the other part is polishing resin, and the boundary between the two is working front. The working resin is responsible for removing most of the ions, while the polishing resin is responsible for removing ions that are more difficult to remove, such as weak electrolytes. The resistivity of ultrapure water produced by EDI systems can be as high as 15-18. 25 MΩ·cm. EDI can be operated either continuously or intermittently.
